In this paper, the performances of the selective Rake receiver and the transmitted reference (TR) receiver are evaluated through computer simulations, for impulse radio ultra-wideband (UWB) systems. The performances of these two receivers are compared by bit error rate (BER), system complexity, and implementation considerations, under IEEE802.15.4a industrial line-of-sight (LOS) and non-line-of-sight (NLOS) multipath environments corrupted by addictive white Gaussian noise (AWGN). The advantages and disadvantages of the two receiver architectures are demonstrated. The simulation results reveal that considering the tradeoff between system performance and complexity, the selective Rake receiver is a better choice in the LOS industrial environments, whereas the TR receiver is a better choice in the NLOS industrial environments. ©2006 IEEE.
